Hi, Response.expires: Sets the expiration date for the current page expressed as the number of minutes from the current time. Usage Sets the expiration date for the current page. The expiration date is used by a HTTP client to determine whether and how long the content of the page can be cached locally. This property is an integer value with its definition defined in the table below. Value Description > 0 The number of minutes from the current server time that the page content expires. = 0 No content expiration is specified. This is generally interpreted by the client as the content expires immediately. Response.expiresAbsolute: Sets the expiration date for the current page to a specific date and time. Usage Sets the expiration date for the current page. The expiration date is used by a HTTP client to determine whether and how long the content of the page can be cached locally. This property is a date value that specifies the absolute date and time the page content expires. If this property is set to null then no expiration date is sent to the client. // Page content expires on Jan. 1, 2006 Response.expiresAbsolute = new Date(2006, 0, 1); // Clear the content expiration Response.expiresAbsolute = null;
